QUESTION
I have a Django app setup with some scheduled tasks. The app is deployed on Heroku with Redis. The task runs if invoked synchronously in the console, or locally when I also have redis and celery running. However, the scheduled jobs are not running on Heroku.
My task:
...ANSWER
Answered 2022-Apr-16 at 01:58If you're on free demo, you should know that heroku server sleeps and if your scheduled task becomes due when your server is sleeping, it won't run.
QUESTION
I don't know why my cron job is not running. Even though if I manually run the custom command, it works. This is what the cronjob file looks like when I do crontab -e.
ANSWER
Answered 2022-Mar-26 at 13:42The cron schedule expression you are using, executes the job every first minute after an hour. For example:
- 15:01
- 16:01
- 17:01
You are probably looking for an expression that runs every minute. If that's the case, you want * * * * *.
QUESTION
We have read https://developer.shopware.com/docs/guides/plugins/plugins/plugin-fundamentals/add-scheduled-task which described how to define a scheduled tasks which runs every x minutes.
Is it also possible to specific the execution time, for example each midnight or every day a 2 am, like in a crontab?
...ANSWER
Answered 2022-Mar-10 at 15:22I'm not aware of such a feature in Shopware core.
The probably most straightforward way would be to add a "real" cronjob like you mentioned, which triggers a CLI-command.
You can encapsulate the logic of the task in it's own service, so that the scheduled task and cli-command both can just use the service (if you want to keep both).

QUESTION
I wanted to run cron and run a few script started at a time set in crontab. I've installed cron on my docker container and wanted to add some crontab lines and cron starting in separate script. Here are fragments of my configuration
supervisord.conf
...ANSWER
Answered 2022-Feb-05 at 02:30Ok, I have to post an answer. I've realized that scripts working well, but it saved reports in system root directory, not on directories that I wanted.
It were because of lack of environment variables More you can read those topic, Where can I set environment variables that crontab will use?
but I've resolved my problem with adding that line at the start of 'run-crontabs.sh' script
QUESTION
I have a Django app deployed in Docker containers.
I have 3 config environnements: dev, preprod and prod. dev is my local environnement (localhost) and preprod/prod are remote linux environnements. It works when using the "public" Redis server and standard config.
But I need to use our own Redis deployed in Docker container in a remote server (192.168.xx.xx) with name container redis_cont.
And I do not really know how to config. I do not know if it is possible? I would appreciate some help.
docker-compose
...ANSWER
Answered 2022-Jan-07 at 13:31Since the containers are not created via the same docker-compose, they won't share the same network. redis_cont just doesn't exist to the services built in the isolated network of your docker-compose.
If Redis container is published on the remote and is accessible using ip:port, you should be able to use it directly in your settings.py. No need to add a new service in your compose file.
To establish a communication between services in the same docker-compose you should use the service name (web, celery-beat, etc in your case) and not the container name.
QUESTION
I have a django application running on Gunicorn and Nginx. There is one request in application which takes 10 min to load the page [There is lot of data to process], i have increased the worker time to 1200 sec for Gunicorn to make it take sufficient time to load the page. it works fine but until that request is getting processed other users are not able to access the application gives :
504 Gateway Time-out nginx/1.21.4
This is my DOCKER
...ANSWER
Answered 2021-Dec-20 at 09:15This might happen because the amount of workers is not sufficient.
Try to increase the amount by adding --workers=4 to the gunicorn call.

I want to run a Python script in a Docker container with crontab, now cron successfully run the python script but it can't find ENV variable given from Dockerfile, when i run echo $DOG from inside the container is shows up expected string "dog" or when ik manaully run the python script /> python dog.py it can find the ENV variables.

Crontab

I'm trying to call a public API endpoint daily on a schedule from AWS. So how I would do this back in the day on a plain old server would be:
...ANSWER
Answered 2021-Dec-07 at 13:37SNS as the target for Eventbridge may be what you're looking for.
SNS topics can have HTTP & HTTPS endpoints as subscribers so this could solve your problem without the need for a Lambda function.
QUESTION
I am trying to write a cron that will run sacct command of slurm for given dates and save it in file. As I don't have much experience with shell script I am not sure how to do it.
I did the following: I created a shell script with the following code (sacct_data.sh):
...ANSWER
Answered 2021-Dec-02 at 06:50The sacct: command not found error means that the command was not found in the PATH. And that is expected as the PATH set in cron environments is really minimal. You can either set a correct PATH variable (see this for instance) or use the absolute sacct path: type which sacct and use the output in sacct_data.sh.
